title: Neonatal cholestasis and focal medullary dysplasia of the kidneys in a case of microcephalic osteodysplastic primordial dwarfism.
abstract: We report on a male infant who presented with intrauterine growth retardation, severe postnatal failure to thrive, microcephaly, facial dysmorphism, and skeletal dysplasia. The clinical and radiological findings are consistent with former descriptions of microcephalic osteodysplastic primordial dwarfism (MOPD) type I/III. In addition to previously published features, multiple fractures of the long bones, severe neonatal cholestasis, and histological dysplasia of the kidneys were found. The boy died at the age of 8 months. The new finding of focal renal medullary dysplasia further supports the hypothesis of a basic defect in tissue differentiation in the pathogenesis of this rare condition.
